The apple dock is kind of pricey, are there any alternatives people can recommend? Also, I'd be happier with an alternative that costs the same but is more useful. Also, can anyone recommend a way I can charge straight from a socket? I've seen pictures of plugs with usb sockets, so I assume a usb cable would go straight from the ipod to the plug, into the mains? I don't like being gouged by apple for extras that should come with the product, but I guess I might have to give in!
